I tested PBO and CO. Here’s what I found:
Hardware list included: AMD Ryzen 7 9800X3D, Corsair iCUE H150i, thermal paste, ASRock X670E, DDR5 memory, SSDs, monitor, keyboard, mouse, GPU, case, OS, and peripherals.
Performance results from Cinebench showed solid scores across different settings, with temperatures staying within normal ranges. The CPU ran at around 47°C at idle and 45°C during overdrive, which is typical.
Using Precision Boost Overdrive and Curve Optimizer improved idle temps slightly but didn’t cause any issues. Scores were generally high, indicating good stability.
The scores you provided suggest the system handled stress well without crashes.
Regarding OC settings: AMD recommends avoiding overclocking on X3D CPUs to prevent cache issues. Extended cache can be more sensitive than regular cores. If you’re concerned, you could stick with stock settings or revert if you notice any instability.
Overall, it seems safe and the build is performing well. Let me know if you need further clarification.
Run the simulation with CO at -30 and no PBO boost. If it becomes unstable, reduce the CO to -30 but keep PBO at +0. If it stabilizes, increase CO slightly (e.g., to -30) and see if performance improves. Higher values like +200 might not always be better—sometimes a lower setting works better.
You're wondering about the effect of the boost and the CO. The boost likely comes from the 200 stage, while the CO helps maintain a lower temperature by preventing higher voltage levels.
I'm not familiar with cache degradation specifically, but increasing overclocking usually means a slight performance boost at the expense of shorter component life. At the cost you pay, do you think a modest performance drop is worth halving the lifespan of your parts? The 3D cache in the 9000 series is positioned under the CCD, unlike earlier versions, so it's still unclear how this affects overclocking. In my view, yes, but ultimately it depends on your perspective.
Lowering CO provides extra flexibility for higher boosts that run more steadily and efficiently. Give it a shot—my friend was using a 5700X, I adjusted only the CO and his cinebench score went up from 12K to 14K while cutting 1C.
you can avoid using pbo entirely and stick with co settings by adjusting your system preferences directly in bios or through control panel. the default values you're seeing are just one option—explore other co levels to see how they affect cooling and component longevity. lowering temperatures can help, but it depends on your specific components and workload.
It doesn't reduce your parts to half, that's not true, the previous note was just a bit dramatic. By default, PBO should have an auto or similar setting you can adjust. I'm not very confident about Asrocks UEFIs.
When I enabled auto mode, the area to select the CO disappeared. I followed these steps: AMD Overclocking, PBO-advanced motherboard, PBO scalar x10 CPU boost clock override, activated positive 25 curve optimizer, set all cores to negative 30.
